Özet
The purpose of this study was to determine the nutritional status of the Cardinal grapes that are grown in Çanakkale. Leaf and soil samples were taken from 18 different vineyards to ensure a uniform sampling area. Although all of the soil samples contained suitable pH values for grapes, levels of organic matter content were found to be low. Lime (CaCO3) content was at an insufficient level in 72% of the soils at 0-30 cm depth and in 61% of the soils at 30-60 cm depth. Phosphorous (P) content was at low and medium levels in 94% of the soils. Potassium (K) was found to be insufficient in 50% of the soils. In both depths, the iron (Fe) content of 33% of soils was lower than the critical level. Manganese (Mn) content was at an insufficient level in 22% of the soils. There were no nutritional problems with respect to zinc (Zn) and copper (Cu) in the soils. Nitrogen (N), calcium (Ca), phosphorous (P), iron (Fe) and copper (Cu) contents of leaf blades were higher than those of leaf petioles. Potassium (K), magnesium (Mg) and manganese (Mn) contents of leaf petioles were higher than those of leaf blades. There were no differences between zinc (Zn) contents in leaf blades and leaf petioles. The N content of 89% of the leaf blades and P content of 61% of the leaf blades was higher than the critical level. There were no nutritional problems with respect to K in leaf blades. The Ca contents of leaf blades and leaf petioles were found to be at insufficient levels. The Mg contents of leaf blades and leaf petioles were found to be sufficient. There were no nutritional problems in leaf blades and leaf petioles with respect to Fe, Mn, Zn and Cu.
